As Dr. Agasa's gaze, Yu Shirakawa, who had worn the three-dimensional mobile device, came to the yard.

This lightweight device gives him an unexpected freshness.

The thick iron sheet and fuel tank were removed, and only two thin winches were fixed on the body, which was as light as nothing.

Aiming at the trunk, shooting out two hook ropes to fix it. The next moment, Yu Shirakawa's body rose into the air.

Dr. Agasa, who was standing beside him, looked worried.

The lightweight model has poor fuel capacity. If it fly in the sky at a high speed for a while, it will be consumed soon.

Without fuel, it means that the injector cannot be used. If the injector cannot be used, it means that the flight angle cannot be adjusted, and you can only simply pull the body with the hook rope.

It is difficult to land, turn, and has a low safety factor.

The difficulty of the operation is not a little bit higher.

Just as he thought of this, Dr. Agasa suddenly looked up.

As his gaze was gradually shocked, the hook began to shrink with a bang, and Yu Shirakawa approached the tree trunk landing point in the air.

The whole process was so stable that it was jaw-dropping.

Although the injector is not used, the operation is better than turning on the injector.

Dr. Agasa was surprised for a moment, and his expression tightened when Shirakawa Yu's body was about to hit the tree trunk.

"Ah, not good! Mr. Shirakawa! Be careful in front!"

——Not using the injector means that the flight trajectory cannot be changed, and you can only fly straight in the direction of the hook rope, and it is very difficult to assist in landing.

It is easy to hit a building and cause accidents.

From Dr. Agasa's perspective, Yu Shirakawa is about to hit the tree trunk now.

However, the latter hummed and gave Dr. Agasa a thumbs up in the air.

Then, Yu Shirakawa under the absolute accurate calculation of [Analysis].

...It was not until the last moment when you were about to touch the tree trunk that you placed your left hand on the winch and turned on the injector switch to the maximum gear.

A strong momentum hits from the left rear.

With this huge thrust, Yu Shirakawa twisted his waist slightly and headed towards the upper right.

In an instant, the flight trajectory was changed, and the faint white exhaust was drawn in a semicircle in the air.

Yu Shirakawa also followed the semicircle circle, lightly avoided the tree trunk, turned half a circle, and landed smoothly on the tree.

While landing, turn off the injector and retract the hook.

The whole set of movements was like training countless times, done in one go without any flaws.

Dr. Agasa widened his eyes and it took several seconds to come to his senses.

"This... Mr. Shirakawa, you're doing it so well..."

He subconsciously exclaimed.

Shirakawa Yu had just shot, and he had no intention of using a poorly-capacity jet from the beginning.

Instead, fly with only the hook rope, and wait until you need to land or turn, you can hit a little jet to coordinate your body and assist in the flight.

It's like those students who practice the second automatic transmission car.

After ignition, release the brakes to move the car. Then, depending on the road slope, do you need to click the accelerator to speed up the hill or something.

Dr. Agasa really didn't expect that a three-dimensional maneuver device mainly composed of an injector can be developed in this way of playing.

"Hey, that's where it's going."

At this time, Yu Shirakawa landed on the tree and then answered Dr. Agasa.

"... Just now, it was just the most basic method of using it. I can also perform a more handsome performance for you. I'll look forward to the doctor!"

He stroked the winch with some smugness, and smiled confidently, giving him a thumbs up again.

But this scared Dr. Agasa.

——Yu Shirakawa does not carry any protective measures. If he uses a more difficult flight method and accidentally falls down, it will be permanent hemiplegia.

Although he plays very well, he is just a physical body.

So Dr. Agasa said anxiously: "Mr. Shirakawa, I think you should come down first and wear it with good protection..."

Not finished speaking.

Click!

The answer to Dr. Agasa was a crisp sound.

Two hooks shot out quickly and fixed them firmly on the tree trunk directly opposite.

Shirakawa Yu jumped gently and jumped off the tree.

Using the brief thrust brought by the jet, he drew an arc from bottom to top in the air and quickly approached another tree.

Dr. Agasa followed him with his eyes tightly, and silently prayed in his heart that there would never be any accidents.

With such a flag bonus, Shirakawa Yu suddenly retracted two hook ropes when he flew into the air and rose to a high place.

With the help of inertia, the whole person flipped his body twice, stretched out his waist quickly, and shot a hook rope to the tree just now.

Then, he twisted his waist flexibly and shot out another hook rope while retracting the previous hook rope.

That's right.

The whole action is like Spider-Man moving, one after another, looking for adsorbable animal.

When the sense of direction is difficult to control, use a little injector.

In this way, I kept repeating this operation, swinging and swinging.

Yu Shirakawa seemed to be playing in the air swing, circled around Dr. Agasa's house, and finally landed steadily on the roof.

Looking at this scene, Dr. Agasa couldn't help but wonder if he was dreaming.

With his rough invention of cutting corners, he could fly around like Spider-Man... Can such a thing happen in reality?

He raised his head blankly and went to see Yu Shirakawa on the roof.

Is Mr. Shirakawa too good, or is it that... his own optimization is really amazing?

Dr. Agasa's heart gradually became active.

Perhaps, after applying for a patent with Mr. Shirakawa, he might be able to become a world-famous inventor with three-dimensional mobility devices?

He touched his bare head and felt a stream of blood rising in his heart.

It's ignited!

On the other side.

A little reorganization is made on the roof.

Yu Shirakawa casually activated the winch switch, hooked the wall of Kudo's house next door, retracted the hook rope in mid-air, and used the injector to buffer gravity and landed steadily on the ground.

Taking advantage of Ke Xue's power to fly around and experience the pleasure of Sangou and Camille, Yu Shirakawa felt quite comfortable.

He caressed the cold winch with love.

He is very optimistic about this light and practical style.

——First of all, you can move three-dimensionally as you wish.

Then there is a super hidden, super portable look.

Finally, there is the hook head of this hook rope.

Since even cement buildings can be hooked, it means that the power of the launching hook cable is not low.

If you take this thing, fire a hook rope at someone and hook it on someone...

Tsk tsk.

That must be a scene with extremely lethality and extremely bloody, right?

Yu Shirakawa felt a little excited.

After applying for a patent and successfully listed, you may be able to recommend this thing to Gin, so that Lao Qin can also enjoy the power of Kexue.

It’s too unfair that the Red Party always has Ke Xue, right?

After such a team idea came to his mind, Yu Shirakawa walked towards Dr. Agasa, and was about to speak up and stoke the doctor to implement a three-dimensional mobile device.

As a result, Dr. Agasa came over directly at this time.

After asking with concern, he made sure he had nothing to do, his eyes lit up:

"Mr. Shirakawa!"

“…According to your statement, the implementation of three-dimensional mobile devices may really have great development prospects!”

“…”
